To fill the system, the valves I9, 26 and 21 Figure 2 is a front elevation of a part of the are closed, and the air cook 33 and the'valve 23 apparatus having a float valve controlled outlet are opened. The disinfecting and deodorizing 30 for mixing the liquid with water in the flush liquid may be-poured into the funnel 2 until tank of a toilet seat. the tank 10 is full, or is filled to the desired level.

The air cock 33 is also delivered to the branch pipes it by a by-pass closed. The water service pipe valve is is opened pipe 20, as will presently be described. Adjustwhereupon water under pressure will rise through ment of the valves l6 of the branch pipes conthe stand pipe l4, through the tank ill, pipe 28, 55

downward through the by-pass pipe 20, the valve 21 of which has been originally opened, and into the distributing pipe to the discharge pipes IS. A modified form of the invention is shown in Figures 2 and 3. In this form of the invention the system as above described, is used with the exception that the distributing pipe 34 is provided with a branch pipe 35 which enters the flush tank 36 of a conventional toiletseat 31. The pipe terminates in a faucet 38 the valve'39 of which may be adjusted to regulate the supply of disinfectant and deodorant to the Water in the flush tank. A valve 46 is disposed in the pipe 35 within the fiush tank and is controlled. by a float 4| sothat each time the tank is flushed lowering ofthe float will open the valve 40 and permit discharge of the deodorant and disinfectant into the water of the flush tank as it recedes." When theswater in the fiush tank rises the float rises with it and when normal water level has been restored will close the valve 48 to shutiofi further supply of the deodorant and disinfectant cto' theflush tank.

A pipe 42is connected at the upper end .to the a pipe 35 in the flush tank and extends through the bottom of the flush tank where itis connected to the flush pipe 43. A valve 44 controls the pipe 42. The valve 39 of the faucet 38 may be closed if desired to manually regulate the supply ofthe deodorant and disinfectant to the urinal by adjustment of the valve 44. A draw ofi cook 45 is connected to the pipe 34 outside of the flush tank so that the disinfectant and, deodorant may be nected to the stand pipe, a manually operable air' c cock connectedwith the tank, a water service pipe connected with the stand pipe, a manually operable valve controlling the service pipe, a by-pass pipe connected with the tank'and with the stand pipe around the water service pipe, a manually operable valve in the stand pipe 'betweenthe service pipe and the distributing pipes, and a manually operable valve controlling the by-pass pipe,

. pipes.

2. Disinfecting and deodorizing apparatus for toilets, urinals and the like, comprising a tank adapted to contain a. disinfectant, a stand pipe connected to the'tank, distributing pipes connected to the stand pipe, a manually operable air cock connected with the tank, a water service pipe connected with the stand pipe, a manually operable valve controlling the service pipe, a by-pass pipe connected with the tank and with the stand pipe around the water service'pipe, a manually operable valve controlling the by-pass pipe, and a valve controlling the stand pipe below the service pipe, adjustment of the last named valve determining vthe rate of discharge of disinfectant from the tank through the stand pipe eitherby gravity when the air cock is opened, or by pressure when the air cock is closed and both the service pipe valve and the by-passvalve areopened.

V 3. Disinfecting and deodorizing apparatus comprising a tank, a stand pipe'connected to the tank, distributing pipes connected to the stand pipe, a second tank elevated above the tank, means for filling the second tank with deodorizing and disinfecting liquid, a valve controlled pipe connecting the second tank with the first named tank, liquid level gauges for both tanks-opening of said valve permitting of the first tank being filled from the second tank, a manually operable air cock connected with the first named tank, permitting of the contents of the tank to escape through the stand pipe when said valve is closed, a valve controlled service pipe, a valve in the stand pipe below the service pipe, and means for by-passing the water from the service pipe. through the first tank into the stand pipe when the air cock is closed to permit water from the service pipe under pressure to dilute the contents of the first tank and supply the sarneto the stand pipe.
